Final 2020 Armyworm Update

Final 2020 Armyworm Update

Armyworm Monitoring Update

September 9

The number of moths has decreased in all locations. Most fields are drained or being drained right now, and the risk of armyworm injury is very low. 

This is our last update for the 2020 season. I want to thank all growers that helped us monitor armyworm in their fields, and the Rice Research Board and Corteva Agriscience for funding this project.

Intrepid® 2F Armyworm Label Update

Intrepid® 2F Armyworm Label Update

You must have the Intrepid® 2F supplemental label in hand as if it were on the container. Intrepid® 2F is the only product with the active ingredient methoxyfenozide registered for use to control armyworm on rice. The registration was complete earlier this year, which left the registrant (Corteva Agriscience) no time to include rice on the label. Corteva Agriscience has made the supplemental label available on the CDMS and Agrian websites. For permitting and label questions, please contact your local agricultural commissioner’s office.
